All objects which have mass have a centre of gravity.
dead-center in the donut hole
No. As a simple example consider a donut shape! The center of gravity lies in the middle where the hole is.
Cute. Are you postulating a hollow body? Like a donut? It's not really possible for real objects.
Center means middle. If you have a circle, the center is the middle.
doughnut hole :)
The the center of the donut , more specifically the center of the hole of the donut. Considering the donut is perfectly symmetrical we only need to look at the geometric center of it , same applies for a hollow sphere like a soccer ball ,the center is indeed in the middle where there is no mass.

The center of gravity is an average of the location of the points of gravity. If you had a flying ring like a Frisbee but without the center, the center of the gravity would be in the hole.

important points about center of gravity
the center gravity
That all depends on the shape of the object and how its mass is distributed. The center of gravity of a solid sphere is at the center of the solid sphere. The center of gravity of a solid cube is at the center of the solid cube. The Earth's center of gravity is at the center of the Earth, and there's certainly plenty of mass there. But the center of gravity of a ring is at the center of the ring ... an open space where the finger goes.
